Spot Image has a cool solution to fill in Gaps in Alaska DEM products... The company is boasting details of a recent completion of thirteen Reference3D geocells over the Chugach National Forest region of Alaska. These geocells are notable, as they provide the first broad area, DTED-2 quality DEM coverage in Alaska. See details here
KML files for all 5000+ rail crossing for the State of Iowa, separated out by county. This information came from a Rail database and the point locations for each crossing are attributed with select fields from out database as well. See http://www.iowadotmaps.com/google/railkml.htm
Alaska State Geo-spatial Data Clearinghouse (ASGDC) provides the community with access to online maps, Data on CDs, and secure GIS data by State agency. The Alaska State Geo-spatial Data Clearinghouse (ASGDC) provides an electronic pathway for the public to access a wide variety of information in the form of maps, images and descriptions about Alaska geo-spatial data. This site is developed as a "node" on the growing framework of public sites across the nation which together constitute the electronic back-bone of the National Spatial Data Infrastructure. See more

Read on for tips on locating and downloading free Alabama DRGs, DOQs, aerial photography and more. See more
I gotta be honest with you... something that drives me up the wall is when public agencies either move or remove a web service, data product or ?? without any explanation or without any paper trail what so ever. Case in point, I have a popular data tip article on GISuser describing and pointing users to the NIMA VMAP data - theses data are... er, were easily accessible via ftp download from the NGA/NIMA website. Now it turns out that all the pointers to these data are broken and users simply get the familiar error page - try hitting this link and you'll see what I mean http://geoengine.nga.mil/ftpdir/archive/vpf_data/v1053.tar.gz.
If you head off to the VMAP 1 boundaries website, then select an area of interest (click on a yellow box), you are then sent to the raster roam page where you are provided with additional information on these data. Then the problem when you click on the FTP download link to access the .tar.gz file. Links are still live, however, the file with 0 for a file size is no longer available.
On the bright side, VMAP 0 data are available for download and you can also grab the data HERE as SHP files. Again, please don't waste your $$ buying the raw data from an online data "eating" resource like the datadepot or others... the same or even more currrent data are easily available via public sites like this.
Anyone have any ideas about this?? An email sent to the contact person provided has no yielded any response.

Thanks to Scott and the crew at DDS in Lakewood, CO for making available this sweet USGS quad index, easily used within Google Earth or google Maps. Simply browse around, locate your quad, click on the bubble icon, then download the free TIF or purchase a high-res digital version or paper map from DDS... freaking awesome! Here's the KML file
Note, the file is large and takes some time to draw fully in G. Maps!
The popular Global Mapper tool has been updated to R 10 today. Notable new features include:
- Added support for importing ESRI personal geodatabase (MDB) files.
- Added support for importing and exporting BigTIFF files.
- Added more control over placement of labels for point features. Now when
- Added support for selecting/changing the layer that features are in when
editing existing features and creating new ones with the Digitizer Tool.
- Added KML/KMZ Super Overlay Support!
and much more! See more details in the announcement or jump to globalmapper.com
The GIS division currently maintains a website that allows free search and view functions for several datasets. In an effort to expand this service, the GIS Division is now providing some of the more frequently requested data in a downloadable format for free on an FTP site. Numerous data layers are available for download including: parcels, topos, centerlines and much more. See http://www.ci.fort-collins.co.us/gis/downloadable-data.php
One of my favorite topics to stir up... free government data! Say what you want about the SDTS format, however, given that data format there's not much you can do about that. But what about access to native USGS SDTS DEM data? You actually do have a say (somewhat) about it and many GIS professionals are still left wondering why these data are only available from a select few commercial data providers (portals)? Read on as we explore this topic a little deeper. See more in this article
ICSM has released a new publication titled ‘ICSM Guidelines for Digital Elevation Data’. The aim is to provide guidelines and recommendations for acquiring elevation data depicting the earth's surface based. It represent a first cut in the preparation of best practice for Australia and have been prepared as an outcome of a review of existing available material from around Australia and selected countries. It was prepared under the auspices of the National Elevation Data Framework (NEDF) initiative. See http://www.icsm.gov.au/icsm/elevation/index.html

I got a weird email message last night that I first thought was junk, then I realized it was actually legit! Google has some new automated system that is flagging potential spam blogs and locking out owners. I was one of the many unlucky ones with my very popular GISuser AnyGeo blog gisuser.blogspot.com being flagged for some reason and locked! Friggin marvelous move Google.
Above is the message that appears... since I was human I entered a code, however, that doesn't resolve the issue.
After searching the web for how to contact the blogger team -- good luck with that one!!! - it seems many others are having the same mis-fortune.
Above is how the blogger dashbopard appears when a blog owner attempts to publish from teh blogger UI
For one, I'm very pi#@#$#@$ed off about this, particularly since I'm off to San Diego for the ESRI UC bnext week and had planned on blogging.. great! So, if anyone from Google happens to read this, maybe contact me (glenn at gisuser.com) and offer up some help or advice. Otherwise, WordPress is sure starting to look good!!

National Geospatial-Intelligence Agency (NGA) is supporting the Federal Emergency Management Agency (FEMA) with unclassified commercial imagery of the recently flooded areas of the American Midwest and is also providing public access to some of the images. You can locate the imagery at www.nga-earth.org and Google Earth users can use their KML reflectors which provide access to the imagery directly in G.Earth.

For a refresher on how to use the streaming web services on the GIS Hub, which allows you to use data without downloading it, please visit http://www.nd.gov/gis/mapsdata/web/. In the section titled, "ArcMap - ArcIMS Web Services" you will find information how you can stream both image data such as aerial photography and vector data such as roads. In the sections referring to "OGC Web Map Services (WMS)" you will find information on how you can use a web service with both ESRI and non-ESRI software.
From http://landsat.usgs.gov/ here is something that may be of interest: A reminder, this acme out of the USGS on April 21, 2008 - Imagery for Everyone By February 2009, any Landsat archive scene selected by a user will be processed, at no charge, automatically to a standard product recipe and staged for electronic retrieval. In addition, newly acquired scenes meeting a cloud cover threshold of 20% or below will be processed to the standard recipe and placed on line for at least three months, after which they will remain available for selection from the archive. Details can be found in the USGS Technical Announcement - .pdf (66.8 KB). http://landsat.usgs.gov/images/squares/USGS_Landsat_Imagery_Release.pdf
The latest imagery is that of the devastation in Myanmar (Burma) - These maps have been produced or facilitated by UNOSAT from public sources. See HERE for data
I see that some of the free "data flogging" websites are now flogging the free 2007 TIGER/Line files (SHP format) for $100+ bucks! OR.... you can always simply go to http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html for your self and take a few minutes to download these data yourself - sounds like a no-brainer to me!
About the data... The 2007 TIGER/Line Shapefiles contain current geographic areas (boundaries of governmental units as of January 1, 2007) and Census 2000 vintage geography. The shapefiles also contain some additional post January 1, 2007 feature updates reported in the Boundary and Annexation Survey (BAS).
